Require SSL on SP when using --saml-secure-setup
    
    If ipsilon-client-install is used with the --saml-secure-setup
    option (which is set by default), only https connections will
    work for authentication.  We are not setting the SSLRequireSSL
    directive though, so we set mellon up to fail.
    
    This patch adds the SSLRequireSSL directive to the SP config
    when --saml-secure-setup is specified.  In addition, we add a
    rewrite rule to rewrite http requests to https for the SP.
